The free end of the bridge-span A is adapted to be adjusted by means of hydraulic jacks applied thereto in the following manner: Boneath the end of each lower chord of the lnidge-span A is a hydraulic jack, comprising a barrel or cylinder ll, supported in upright position upon the corresponding supportingpier A" and a piston or ram l3. As shown, the barrels or cylinders 13 are supported by flanges or collars B formed thereon at about the middle longitmlinally thereof, which rest upon the caps A, suitable wells or openings being formed in the piers A to receive the lower ends of said cylinders or barrels. \Vater under pressure is delivered to the barrels or cylinders of thejaeks from anysuitable source ofsnpply (notshown) through pipes I) and may be discharged therefrom through waste-pipes b in controlled communication with said pipes I). Said jack-cylinders B are also provided with pipes Z1 controlled by valves b and which communicate with the lowerends of said cyli ndcrs. Means are thus provided for removing from said cylinders any sediment which may accumulate therein. Secured to the upper ends of the rams or pistons B are heads l), which are fitted to and are longitudinally movable in suitable guides formed on the interiors of the towers A and which are in alinement with said rams or pistons B. As shown, the heads 1) are secured to the rams or pistons 13 by pins D, fitted to suitable holes or openings formed in lugs or ears (Z, formed on said heads, and to yokes (1, formed in the ends of said rams or pistons. The pins D are seen red in the yokes d by means of pins d As shown, also, the heads D are guided by means of blocks D of which the upper blocks are rigidly secured to said heads l) and are preferably formed integral therewith, and the lower blocks are carried on the pins D, which engage guide grooves (i formed partly in the plates A and partly in plates I)", secured to the interiors of said towers A" and which are disposed so as to form, in effect, continuations or extensions of the plates A". The heads D and the plates D are preferably made of cast-steel. The heads 1 D, carried on the rams or pistons B, are connected to the ends of the lower chords of the bridge-span A by means of links D", which are pivoted upon the pins 1.) at one end and the opposite ends of which are pivoted to pins (1", secured in the ends of said lower chords of said bridge-span. Said hydraulic jacks are thus applied directly to the bridgespan and are sufticiently powerful to raise the same.

The invention also comprises means for locking the heads l i to the towers, so that they will be supported independently of the hydraulic jacks, which we will now describe.

livoted to the heads D are dogs or pawls E, on which are formed teeth 14, which are adapted to engage teeth 0 on the towers. As shown, the teeth e are formed on the guide-blocks D on both sides of the guidegrooves (72, formed therein. The upper guide-blocks D project through openings formed in the lowerendsof thepawls or dogs E. Pivotal movement to effect engagement and disengagementof the teeth eof the pawls E with the teeth e on the towers is imparted to said dogs or pawls by means of links (9, one end of each of which is pivoted to one of the pawls E above its pivotal point, their opposite ends being pivoted to yokes E. The links 0' thus form toggle-levers, which may be flexed to disengage the pawls E from the teeth, 6' by raising the yokes E or straightened to effect engagement of said pawls with said teeth by lowering said yokes. The yokes .E are provided with shanks c", which are fitted to and are longitudinally movable in holes or guides formed in the heads l). Thus the same movement will always be imparted to both of the pawls on each head. The yokes E are raised and lowered by means of ropes E applied thereto and which are adj usted to sheaves E revol ubly supported ad jacent to the tops of the towers A In the preferable form of the device means are provided for securing the pawl-actuating toggles in flexed position. Simple means for this purpose consist of arms E, pivoted upon the yokes E, which are adapted to be swung into engagement with a rigid portion of the head when said toggles are fully flexed. in the preferable construction shown the arms E are rigidlysecured to the pivot-pins in the yokes E and are provided with laterally-projecting arms a, to which the ropes E are at tached. The free ends of the arms E bear upon the tops of webs on the heads D, and they are provided with lateral projections e, which project therefrom, so as to strike against the shanks e of the yokes E and limit the pivotal movementof said arms E. The upward movement of the yokes E is limited by means of a stop 6 on the shank c" of said yokes, the position of which is such that the pawls E will not be retracted back. of their pivotal points. The pawls E being in engagement with the teeth 6 on the towers, it is obvious that a strain or pull on the ropes E" in the proper direction will operate to raise the yokes E and will also operate to turn the arms E pivotally until the projections c strike the shanks e of the yokes E, in which position the arms E are substantially vertical. Again, the toggles being flexed a strain on the ropes E in the proper direction will operate to release the locking-arms E and to draw down the yokes E, thus straightening said toggles.

lVhon it is desired to Vary the vertical ad- TIC justment of the span A, said span is first raised slightly by means of the hydraulic jacks in order to facilitate the disengagement of the pawls E from the rack-teeth e on the towers and to support-said span. When said pawls areso disengagedfrom said towers, said span is then raisedor lowered to bring the same into desired vertical adjustment by means of the hydraulic j acks and when in de-,

sired vertical adjustment the pawls E are,

again thrown into engagement with the rack,- teeth c on the towers, thereby securely locking said span in position and relieving said jacks from all strain due to the weight thereof.
